Professional Node.js API Development PartnerAPI Development
We build production-grade Node.js APIs that ship in 12 weeks. Fixed price, senior engineers, full ownership.
IRPR is a professional Node.js API development partner. We build REST and GraphQL APIs with Express, Fastify, Prisma, PostgreSQL, Redis, and Docker. Every API is designed for 99.9% uptime and sub-50ms response times.
We ship your first API version in 8-12 weeks. Pricing is fixed from day one, typically $80K-$250K depending on scope. We handle compliance for healthcare (HIPAA), fintech (PCI-DSS), and SaaS (SOC 2).
Companies that hire us include CTOs launching a SaaS MVP, product teams integrating third-party data, enterprise architects migrating from monoliths to microservices, and founders building internal tools that need real-time sync.
Types of software we ship.
REST API Development
Stateless REST APIs with Express or Fastify. Includes OpenAPI docs, rate limiting, and JWT auth.
GraphQL API Development
GraphQL APIs with Apollo Server or Yoga. Supports subscriptions, federated schemas, and automatic persisted queries.
Microservices API Development
Decoupled Node.js services with message queues (RabbitMQ, Kafka) and containerized deployment on Kubernetes.
Third-Party API Integration
Connect to Stripe, Salesforce, HubSpot, Twilio, or custom SOAP/REST endpoints. Handles retries, caching, and webhooks.

Why hire a professional Node.js API development partner
A generic freelancer builds one endpoint. IRPR builds a production API that scales.
IRPR has shipped 200+ Node.js APIs for clients in healthcare, fintech, and SaaS. We use Express, Fastify, Prisma, and PostgreSQL by default. Every API includes automated tests, CI/CD pipelines, and monitoring with Sentry and Datadog.
Our team of senior Node.js engineers averages 10+ years of backend experience. We write code that handles 10,000 requests per second without crashing. We document every endpoint with OpenAPI 3.0 and provide Postman collections for your QA team.
IRPR vs. hiring a freelance Node.js API developer
One delivers endpoints. The other delivers a system that runs in production.
Freelancers often work alone, have limited bandwidth, and disappear when they get a bigger client. IRPR is a team of 10 senior Node.js engineers who work together on your API. We have backup coverage, code review, and a project manager.
We use a fixed-price model based on the Roadmap phase (week 2). You know the exact cost and timeline before we write a line of code. No hourly billing surprises. No scope creep without your approval.
- Single developer, no backup
- Hourly billing, unknown total cost
- No automated tests
- No CI/CD pipeline
- No monitoring or alerting
- No API documentation
- Team of 10 senior Node.js engineers
- Fixed price from Roadmap phase
- 100% test coverage on critical paths
- CI/CD with GitHub Actions + Docker
- Sentry error tracking + Datadog metrics
- OpenAPI 3.0 docs + Postman collections
How we build your Node.js API in 12 weeks
We follow a four-phase process that de-risks every step.
Phase 1 (Week 1-2): Roadmap. We define all endpoints, data models, auth flows, and integration points. You get a fixed price and timeline. Phase 2 (Week 3-6): Core API. We build the authentication layer, database schema, and first 10 endpoints. You see running code.
Phase 3 (Week 7-10): Integration and testing. We connect to your third-party services, run load tests, and fix bottlenecks. Phase 4 (Week 11-12): Deployment and documentation. We deploy to AWS/GCP, set up monitoring, and hand over full ownership.
What ships with every Node.js API
You get more than code. You get a production-ready system.
Every API includes a CI/CD pipeline on GitHub Actions, Docker containers, and automated tests. We set up Sentry for error tracking and Datadog for performance monitoring. You get OpenAPI 3.0 documentation and a Postman collection for your team.
We also include a deployment guide, environment variable templates, and a runbook for your ops team. You own everything from day one. No lock-in, no license fees, no recurring payments.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with Docker
- Automated unit and integration tests (Jest)
- Sentry error tracking with alerts
- Datadog performance and uptime monitoring
- OpenAPI 3.0 documentation (Swagger UI)
- Postman collection for your QA team
- Deployment guide and environment templates
- Runbook for your ops team
- Full ownership with MIT license
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
Every engineer on your project has 10+ years of Node.js experience. No juniors, no offshore teams, no code monkeys. You talk directly to the engineer building your API.
12-week delivery guarantee
We ship your first API version in 8-12 weeks. 98% of our projects finish on time. If we miss the deadline, we discount the next phase by 20%.
Full code ownership
You own every line of code from day one. No license fees, no recurring payments, no vendor lock-in. We hand over source code, documentation, and deployment scripts.
Production-ready from day one
Every API ships with CI/CD, automated tests, monitoring (Sentry, Datadog), and documentation (OpenAPI 3.0). Your operations team can deploy and maintain it without us.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliant APIs. We have templates for audit logging, encryption at rest and in transit, and access control. No compliance surprises.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
